MAGNETIC PROTECTOR FOR. SHIPS.

Specification of Letters Patent.

Application led July 20, 1917. Serial No. 181,688.

To all whom t may concern Be it known that we, J oHN PIES, a subject of the' King of Hungary, resident of Orangeburg, county of Rockland, and State of New Yor and SOPHIE PIES, a subject of the King of Hungary, resident of Orangeburg, county of Rockland, and State of New York, have'invented certainnew and useful Improvements Ships, of which the following is a specification.`

This invention relates to improvements in attachments to the hulls of ships, by means of which submerged torpedoes, mines and the like may be attracted and held at a distance from the hull of thevessel, rendering them innocuous, thereby reventing damage.

The principal object o the invention is to provide such devices in forms which may be applied to ships as presently constructed, without necessitating any. material change in the hull thereof, and which includes the provisionv of extended buoyant elements whereby the magnetic attractors are held at a safe distance from the hull.

A further object is to charge the magnetic attractors with a current derived from gen erators carried on. board the vessel as to cause the same to operate through a relatively wide range of action, the power of the divert a torpedo from its course, attracting the same until contact is made and thence holding it extended.

These and other like objects are attained bythe novel construction and combination of parts hereafter 'described and shown in the accompanying drawings, forming a ma terial part of this disclosure, and in which- Figure 1 is aside elevational view of a ship indicating the attachment of the invcntion.

Fig. 2 is a top plan view ofthe same.

Fig. 3 is an. enlarged front View indicating the application of the invention, both in an extended and folded position, and

Fig. 4 is a diagrammatie'view illustrating the electrical and magnetic elements, together with their connections.

The ship 10, here shown to be of conventional type and provided with the usual appendages throughout, has secured at a convenient point upon its deck raised elements 11, in which are contained powerful hoists or Winches not shown) and from which lead cables 14, running over pulleys 15 and 16, the latter being attached to the in Magnetic Protectors vfor unwales of the ship and at either side thereof, the cables being attached at their outer ends to the outermost floats adjacent to the hooked brackets 18, supported by the floats 20, 21 and 22, which are held spacedly apart by interengaging connections 24 and strips 25, the inner ends of which are connected by brackets 27 with the hull of the Vessel in the manner of a hinge, thereby permitting the same to be raised into a substantially vertical position as indicated by the broken lines shown in Figs. 2 and 3, or extended at length as Shown by the full lines in the same view.

rlhese floats, which are preferably hollow metallic tubes with oval pointed ends, are made in two sections insulated from each other by plates 30 of non-magnetic material,

, and are capable of sustaining the weight of pairs of magnets 32 and 33 arranged in tandem, from the lower of which extend the links of a chain cable 35 to any desired distance.

ln the diagram shown in Fig. 4, a generator 40 is connected by a conductor 41, to the upper pair of magnets 32, joined by the connection 42, the return current from the lower magnet 33 of which passes through the wire 44 to the generator.

A secondary current, formed by the battery 47 and controlled by the switch 48, is connected by the wire 50, with the chain 35, the return from which comes through the wire 51 upon the close approach of, or contact with a metallic body, and causes an audible signal, as the bell 52, to be sounded upon the approach of any electrical conductor, as a nonncing .its dangerous proximity.

Obviously, the generator 40 will be operated only when within a zone of danger, and it will be equally apparent that the effects of the magnets 32 and 33 as communicated to the chain 35may be suilicient floating mine or torpedo, hence anraten-tea Een., a, raie. Y

to attract any metallic article and cause it diameters arranged in spaced relation upon said arms, lates of nonmagnetic material insulating t 1e sections of said floats from each other, pairs of powerful electromagnets arranged in tandem and carried by the outermost of said. floats, connections between said source of electrical power and said electro-magnets, whereby the same are energized, a chain cable extending from the lowermost of said electromagnets into the water 10 to a predetermined depth, for attracting magnetic material in their neighborhood, cables connecting the outermost of said floats with the ship, and hooks on said brackets engaging the uppermost of said electromagnets for allowing a raising and lowering of the floats as, occasion requires.

In testimony whereof we have ailixed our signatures.

JOHN PIES. SOPHIE PIES.
